MOUNTING FOR CAR-WHEEL JACKS.

Application filed December 14, 1923. Serial No. 680,712.

ably holding a car wheel against movement relatively to a supportingrail and which also provides means whereby a jack may be supported in adesirable position with respect to a part of the wheel supportingstructure.

A further object is to provide a device of the character described inwhich the means for holding a car wheel against movement relatively to asupporting rail can be adjusted to hold car wheels of various sizes ona. rail of any one of a plurality of difierent sizes.

A further object of the invention is to provide a device of thecharacter described which affords facilities for releasably holding ajack in adjusted position thereon.

Other objects and advantages will be ap parent from the followingdescription, considered in conjunction with the accompanying drawings,in which-- Figure 1 is a view mainly in side elevation and partly invertical section, showing a mounting embodying the invention in positionto secure a car wheel to a supporting rail, the jack which may besupported on the mounting being omitted,

Figure 2 is a view at right angles to Figure 1, showing the mounting inrail securing position and showing a jack thereon, the jack being shownmore or less diagrammatically, the rail being shown in section and a rimportion of the wheel being broken away.

Figure 3 is a fragmentary sectional view, taken substantially along theline 3-3 of Figure 1,

Figure l is a section along the line 4El of-Figure 1,

Figure 5 is a perspective view showing a rail clamping member or prisedin the device,

Figure (3 is an enlarged fragmentary section substantially along theline 6- 6 of Figure 2, and

Figure 7 is an enlarged perspective view showing a spring latch memberwhich is comprised in the device.

Referring now to the drawings and particularly to Figures 1 and 2thereof, 1 designates a track trail supported on ties 2. 3 is a carwheel which is supported on the rail 1 in rolling contact with thelatter, and which is mounted on an axle 4-. The latter ordinarily isrotatably supported adjacent to its ends in journal boxes, such as thatindicated at 5 in Figures 1 and 2, the journal boxes being attached tothe car frame (not shown) in any suitable known manner as by means ofmembers such as those indicated at 6 and 7 in Fig. l.

The parts described so far are parts of a jaw which is comrailway car ofordinary construction and form no part of the invention.

it is desirable that the wheel 3 shall be secured against movementrelatively to the supporting rail when the journal box 5 or any otherpart of the car wheel carrying structure has been elevated slightlyabove normal position for any purpose, as for in stance to permit of thereplacement or repair of the. brasses within the journal box. Otherwise,injury to a workman engaged in repairing or replacing the brasses'withinthe journal box may result.

The mounting embodying my invention includes'mcans for releasablysecuring the wheel to the supporting rail. and also includes means forsupporting a suitable shank in position to exert upward pressure againstthe journal. box for the wheel carrying axle, as will be understood fromthe following.

In carrying out the invention in the form now preferred by me, I providea base designated generally 8 which includes. an elongated plate member9 superposed upon a flat supporting loclr 10 and extending aconsiderable distance beyond one marginal edge of the supporting: block,whereby the plate member 9 will be substantially horizontal when thesupporting block 10 is disposed upon one of the ties 2 so that theextending portion of the plate member 9 is in abutting relation at itsend with the adjacent face of the web portion of the rail 1 theextending portion of the plate member 9 being positioned above the levelof the base flange of the rail as clearly shown in Fig ures 2, 3 and 4:.A stationary clamping member or jaw 11 is disposed upon the extendingportion of the plate 9 and is rabbeted at 12 to engage not only with thead jacent face of the web portion of the rail but with the under andouter faces of the adjacent portion of the rail head. The jaw 11 isfixedly secured to the plate 9 by screws 13 or like securing devices.

The upper end portion of the jaw 11 is provided with a pair of oppositelateral. wings or extensions 14: which extend in close abutting relationto the rail head and terminate in end portions 15 which extend above thelevel of the rail. Each of the end portions 15 has a horizontal slot orelongated opening 16 therein, which slots or elongated openings arepositioned in a plane slightly higher than the level of the upper faceof the rail head.

A pair of movable clamping members or jaws 17 are provided to cooperatewith the stationary jaw 11 for the purpose of securing the plate member9 to the rail and for holding the wheel flange against axial movementrelatively to the rail. Each jaw 17 comprises a block 18 which is cutaway at 19 to engage with the outer face of a portion of the under faceof the adjacent part of the rail head and which is provided with a shank20 extending from the upper end portion thereof across the upper face ofthe rail head through the slot or elongated opening 16 of one of theextensions 15, the free end portion of said shank being screw threadedfor engagement with an adjusting nut 21 and a washer 22 preferably beingdisposed upon the shank between the adjusting nut and the extension 15.Each block 18 carries a clamping arm 23 which is pivotally attached atits lower end to the block 18 by a bolt 2 1- or the like to swing abouta horizontal axis in a plane contiguous to the outer face of the blockand to the outer face of the rim flange of the wheel. Each clamping arm23 may be releasably held in a desirable angular relation to thehorizontal by tightening the bolt 2% so that the clamping arms 23 may bepositioned in engagement with the outer faces of the flanges of wheelsof different diameters. A stop member on each of the blocks .8 limitsthe swinging movement of the associated clamping arm 23 in one directionabout the axis of the pivotal connection Qti'. for a purpose which willpresently appear.

A standard 26 arising from the plate 9 extends vertically for part ofits length against the outer face of the jaw member 11 and is secured tothe latter by screws 27 or like securing devices. The standard 26 isformed above the level of the tread or rim portion of the wheel with anend portion 28 which is inclined toward the plane of the wheel and isprovided with a threaded opening 29 for engaging the threaded rod orstem 30. The latter is provided at its outer end with a handle 31 and atits inner end with a clamping head 32 which is swivelel thereon. Thelatter is adapted to engage with the inner peripheral wall of the rimportion of the wheel when the adjusting screw rod 30 has been turneduntil the clamping head 32 has been forced against the inner peripheralwall, of the rim portion of the wheel.

The plate 9 is provided with a pair of spaced apart parallel guide bars33 extending thereon alon the longitudinal edges of the plate for partof the length thereof, the guide bars 33 being joined integrally withthe plate or formed separately and secured thereto in any suitable knownmanner, as ocsircd. The guide bars 33 have the confronting faces thereofundercut or grooved as indicated at 341- to engage with opposite lateralextensions 2 or portions of a base or bottom member 35 of a jack 36which rests upon the plate 9 and is slidable on the latter toward andaway from the jaw member 11. The jack 36 may be of any suitable known orpreferred type of construction having the lateral cxtensions or portionsat the lower end thereof for entering the grooves 34- of the guidemembers The jack therefore is shown more or less diagran'nnaticall v inthe drawings. However, such jack preferably includes a handle 37 whichis adapted to be grasped conveniently to effect sliding movement of thejack on the plate 9 between the guides 83 and the base or bottom memberof the jack preferably has a laterally extending flange portion so thatthe opposite lateral extensions for engaging the grooves of the guides33 will be provided by portions of such laterally extending flange whenthe ack aas been turned about its axis to any possible position. Thejack may be held against movement from adj ustcd position along theguides 33 in any suitable known manner, preferably through the. agencyof a substantially U-shaped spring latching clip 38 which is formed of ama terial possessing inherent resiliency and having arms normally heldin divergent rclation because of the resiliency of the componentmaterial, whereby 'ircssure will be exerted on the jack and on one ofthe guide members 34 when the latching member 38 is inserted in themanner of a wedge between the body of the jack and the adjacent face ofthe guide member. (inc of the. arms of the latching member iireferablyis fashioned at its outer extremity to provide afinger ere.

hold or handle. 39 for convenience in manlpulating the latching memberto place -it in latching position with respect to. the

jack and guide bar or to remove the latching member from latchingposition to release the jack. i

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The wing extensions 14 ofthe stationary jaw member 11 are of sullicient length that the elongatedopenings 16 may be spaced apart a distance suiiicientto permit of theshanks 20 of the movable clamping blocks being extended across a rail atopposite sides of the point of rolling contact of a wheel with the railand then extended through the elongated openings 16. The distancebetween the shanks 20 of the movable clamping blocks may be varied bymoving such shanks on the rail 1 and along the elongated opening 16 sothat the clamping arms 23 will be positioned for engagement with theouter taces of the rim portions of wheels of different diameters. Thestop members 25 prevent outward swinging movement of the clamping arms28 beyond position to engage with the adjacent face of the rim portionot a wheel of the largest diameter with which the device is adapted tobe used. lVhen the nuts 21 have been tightened the clamping block andthe stationary jaw 11 will be clamped against opposite sides of the railhead and the plate 9 will be held against movement relatively to therail. At the same time, the clamping arms 23 will be held in closeengagement with the inner taces of the rim portions of the wheels thustending to hold the rim flange of the wheel against the inner face ofthe rail head and cooperating with the clamping head 32 when theadjusting screw 30 has been tightened to hold the wheel against upwardmovement from the rail. This clamping action on the wheel also tends toprevent rotation thereof. The jack 36 can then he slid on the plate 9between the guides 33 to a desired position and after being securedagainst movement relatively to the plate 9 by use of the latching member38 may be manipulated to exert upward pressure on the journal box 5.

Obviously, my invention is susceptible of embodiment in forms other thanthat illus trated in the accompanying drawings and I therefore consideras my own all modifications and adaptations of the form of the deviceherein described as fairly fall within the scope of the appended claims.

Having thus described the invention, what I claim is 1. A device of thecharacter described comprising a base adapted to be positioned upon arailway track at one side of a track rail and in abutting relation tothe latter,
